background: mammographic density has been recognized as a risk factor for breast cancer,  but  the  association between  potential  effective factors and  mammographic density has not been fully studied in asian women. we conducted a study to investigate the association of mammographic breast   density with several menstrual and reproductive characteristics. m ethods: screening  mammography  wa...

results in patients with high breast densities, malignant cases (61.2%) were significantly more in comparison to patients with low breast densities (37.3%) (p= 0.007, or=2.66 95% ci=1.29-5.49). after adjusting for age, density was associated with malignancy in age groups <46 years (p=0.007), and 46-60 years (p=0.024) but not in age group >60yrs (p=0.559). adjusting for menopausal status, densit...

The mammographic density belongs to risk factors for breast cancer. The increased density enhances the risk of interval breast cancers and it also increases the number of false negative as well as false positive results of the mammography. The increase in the mammographic density during the hormone replacement therapy is not identical with the enhanced mammographic density, which is a risk fact...

To the Editors: In their recent article, Boyd et al. (1) sought to examine whether the increased risk of breast cancer associated with postmenopausal hormone therapy was mediated through mammographic density (percentage mammographic density) in three screening programs. They did this by comparing the relative risk of breast cancer associated with hormone therapy with and without adjustment for ...

BACKGROUND Effects of dietary factors, such as adherence to Mediterranean diet, multivitamin-multimineral supplements use and alcohol consumption on mammographic breast density, an important biomarker of breast cancer risk, are not sufficiently consistent to elaborate preventive recommendations. This study aims to investigate the association between current diet and mammographic density. METH...

Mammographic density is one of the strongest predictors of breast cancer risk. Recently, it has been suggested that reactive oxygen species may influence breast cancer risk through its influence on mammographic density. In the current study, we addressed this hypothesis and also assessed if the association between carotenoids and breast cancer risk varies by mammographic density. We conducted a...

BACKGROUND In the Copenhagen mammography screening program from 1991 to 2001, mammographic density was classified either as fatty or mixed/dense. This dichotomous mammographic density classification system is unique internationally, and has not been validated before. PURPOSE To compare the Danish dichotomous mammographic density classification system from 1991 to 2001 with the density BI-RADS...

PURPOSE Mammographic density is a strong and highly heritable risk factor for breast cancer. The purpose of this study was to examine the extent to which mammographic density explains the association of family history of breast cancer with risk of the disease. SUBJECTS AND METHODS We carried out three nested case-control studies in screening programs that included in total 2,322 subjects (1,1...

BACKGROUND Mammographic density is a strong risk factor for breast cancer. Apart from hormone replacement therapy (HRT), little is known about lifestyle factors that influence breast density. METHODS We examined the effect of smoking, alcohol and physical activity on mammographic density in a population-based sample of postmenopausal women without breast cancer. Lifestyle factors were assesse...
